    • The invention concerns a reversible rotary compressor which can compress refrigerant in either of the forward and reverse directions, without providing a valve mechanism in a closed container. In a reversible rotary compressor including a cylinder, a rolling piston, and a slide vane, two inlet/outlet ports are formed in a space between the outer surface of the rolling piston and the inner surface of the cylinder in a state that the two inlet/outlet ports are disposed on both sides of the slide vane. The two inlet/outlet ports are closed by the rolling piston when the rolling piston is positioned at the top dead center and fully opened when the rolling piston is positioned at the bottom dead center. Two refrigerant pipes, coupled with the inlet/outlet ports, are provided in the side wall of the cylinder. The two refrigerant pipes are closed by the rolling piston when the rolling piston when the rolling piston is positioned at the top dead center and fully opened when the rolling piston is positioned at the bottom dead center.
    • 本发明涉及一种可逆式旋转式压缩机,其可在向前和向后两个方向压缩制冷剂,而不在密闭容器内提供阀机构。 在包括气缸,滚动活塞和滑动叶片的可逆旋转压缩机中,在滚动活塞的外表面和气缸的内表面之间的空间中形成两个入口/出口,该两个入口/出口在两个入口 /出口设置在滑动叶片的两侧。 当滚动活塞位于上止点时,两个进/出口由滚动活塞封闭,当滚动活塞位于下止点时,两个进/出口关闭。 在气缸的侧壁上设置有与进/出口相连的两个制冷剂管。 当滚动活塞位于上止点处时,当滚动活塞处于滚动活塞时,当滚动活塞位于下死点时,两个制冷剂管道被闭合。
